[Hodgkin's disease: from gross tumor volume to clinical target volume, firm data and unresolved problems]

The purpose of this article is to specify the target volumes, using ICRU criteria in the treatment of Hodgkin's disease. Because of the complexity of irradiation fields, the literature was carefully reviewed. However, with the variations of the recommendations and in the absence of large-scale studies, usual criteria can still be used. A consensus about the precise specification of the target volumes on CAT scan is still urgently awaited.
